Just do 12 times 4 this should get you 48 and thats the number

To solve for x, set up an equation like below...
.25(x) = 12
Divide by .25 from both sides and you get...
x = 48

Check..
.25(48) ?= 12
12 = 12

We did it! :D

Translate to a proportion and solve.<br> 148.5 is 59 1/5% of​ what?
lesantik [10]

The actual value is 250.84 .

Formula

Percentage calculation =(given value/total value)*100

let the actual value is "x"

percentage we known is 59 1/5% (59.2%) and 59.2% of x is 148.5.

for the percentage,

x*59.2% =148.5

x*59.2/100=148.5

x=(148.5/59.2)*100

x=(2.5084)*100

x=250.84

The actual value is 250.84 .

Seventh grade &gt; EE.11 Probability of independent and dependent events NED
ella [17]

Step-by-step explanation:

each combination of 2 specific numbers has the same probability. there is no difference in probability between the individual numbers.

remember, a probability is always desired cases over all possible cases.

we have 4 different possible outcomes every time we spin the spinner.

to get a specific number has the probability of 1/4, because we want 1 specific outcome, and have in total 4 different possibilities.

now, we spin a second time. the probability to get a specific number is again 1/4.

but, if we consider both events to be connected, when we want to know the probability to get 2 specific numbers when spinning twice, we have to multiply the individual probabilities :

1/4 × 1/4 = 1/16

so, the probability to land first on a 5, and then secondly on a 2 is 1/16.

the same as for landing first on a 3, and then on a 5.

the same as for landing first on a 4, and then on a 4 (again).

that is because the individual spin results are independent. the result of the first spin does not impact in any way the result of the second spin (in contrary to e.g. pulling multiple cards without returning the previously pulled cards).

X + 2y = 10
Crazy boy [7]

Answer:

(-12,11)

Step-by-step explanation:

x + 2y = 10

3x + 4y = 8

(-2)x + (-2)2y = (-2)10

3x    + 4y       = 8

-2x - 4y = -20

3x  + 4y = 8

Add to eliminate:

x = -12

Substitute x to solve y:

x + 2y = 10

(-12) + 2y = 10

-12 + 2y = 10

2y = 10 + 12

2y = 22

y = 22 ÷ 2

y = 11

Check:

x + 2y = 10

(-12) + 2(11) = 10

-12 + 22 = 10

10 = 10
